Something doesn't sound right here, over the many years I have seen a lot of mishaps regarding chainsaws, I have seen chainsaws get downright hot to the point of smoking the oil soak sawdust and seen spilling fuel on the exhaust causing a flareup or working overhead and having the gas cap vibrate loose but I never heard of a chainsaw exploding while using. Very little information is public. Was he filling a hot chainsaw up with fuel or was he actually using it? It seems they are being pretty lose with the word explosion, more likely burst'ed into flames from a leak (85% 3rd degree burns)?
Coroner Scott Grim later said the man was doing work on his own property when the chainsaw exploded.
